Star Sapphire has more common sense than other fairies, being a bit calmer, wiser, and also avoiding lights. She lets her other two partners (Sunny Milk, Luna Child) do all the hard work for her. Unlike her partners, she has the most bizarre sense of perception. Sometimes, things that would cause Sunny and Luna to panic, such as an imminent incident or seeing a mountain of human skulls, Star seems to find fun and exciting. She has the ability to detect moving things no matter their distance.
